Why do all the buildings (skyline) in Vancouver, Canada look the same?

The buildings in the picture look to me like they're located in the Yaletown district of Vancouver. This is a fairly newly revitalized area of Vancouver. The construction boom of the 80s and 90s in that area did result in many somewhat similar looking high rise condos and apartments. The attached photos are of two other new Vancouver skyscrs that might interest you. The first is Vancouver's tallest building, the Shangri-La at 62 stories and the second is One Wall Centre, Vancouver's second tallest building at 48 stories.
